Article IntroductionUsing Python to print Chinese in the console is not garbled, it's been a lot of pythoner problems, and even a lot of Python veteran often puzzled. The reason is that from the general Web page, database or text from the external data source crawling over the content, need to pass the correct codec to normal output, and
In the process of learning and developing the use of language looping statements, various shapes are often printed to verify the proficiency of the looping statements, followed by the use of Python to print a variety of shape exercises.In the following example: variable i controls the outer loop (number of graphic lines), J controls the number of spaces, K controls the number of asterisks (*)1. Printing tri

Preface
Python: "Everything is an object !", Recently, we found that the usage of print in python3 and python2 is many different. In python3, parentheses are used and four spaces are used for indentation (this is not necessary, but you 'd better do this ), in

In Python, when the code is long, want to see the code execution result in the Pycharm-console console or Python's own idle shell window, print some characters and so on, there are no line breaks between many lines affecting the viewing effect, so how to print a few lines of space in Python:Three different ways:1. Use line break "\ n":1
1 Logging Module IntroductionLogging module is a python built-in standard module, mainly used for output log, you can set the level of output logs, log save path, log file rollback, etc., compared to print, has the following advantages:
You can only output important information in release version by setting different log levels, without having to display a lot of debugging information;
Brother I'm back again, haha · Haven't come to write a blog for a long time, now slowly make up the former! Recently learning Python, so you will update some of the problems encountered in learning.Today's content is the function of a simple script written before the shell is implemented with Python: Select the corresponding menu item and print the status informa
One, let the print () function does not break the line
In Python, the print () function defaults to newline. However, in many cases, we need output that does not wrap (for example, in an algorithmic race). So how do you do that in Python?
It's actually very simple. As long as you specify that the end parameter of the

Assignment Statement
The vast majority of assignment statements are simple, but some features should be specifically remembered:
The Python value assignment statement stores the object reference value in the element of the variable name or data structure. The value assignment statement always creates an object reference value, instead
Copying objects, so Python variables are more like pointers than data st
